[smartmontools-support] DEFAULT -n standby not working for Adaptec Raid

[Sagar.Biradar at microchip.com]

Hi David,
Probably you are looking for this

aacraid,H,L,ID - [Linux, Windows and Cygwin only] the device consists of one or more SCSI/SAS or SATA disks connected to an AacRaid controller. The non-negative integers H,L,ID (Host number, Lun, ID) denote which disk on the controller is monitored. Use syntax such as:
smartctl -a -d aacraid,0,0,2 /dev/sda
smartctl -a -d aacraid,1,0,4 /dev/sdb

Option '-d sat,auto+...' is implicitly enabled to detect SATA disks. Use '-d scsi+aacraid,H,L,ID' to disable it.
On Linux, the following entry in /proc/devices must exist: aac. Character device nodes /dev/aacH (H=Host number) are created if required.
On Windows, the device name parameter /dev/sdX is ignored if '-d aacraid' is specified.

I am adding Balaji and Uday, from the apps team to help with exact IOCTLs and possible alternatives.
Balaji and Uday – could you please help David with tools/IOCTL to find the powerstate of all the drives participating in a volume?

Thanks
Sagar

Or in fact how to ask the raid controller about the power status of each logical device as the RAID config is for power management by logical device.

hdparm -C /dev/sdb reports standby for the logical device anyhow when the device is in Active status (which is wrong)

We need to know how to ask the raid controller the state of each of the *physical* devices which make up the raid array.
